Roblox Murder Mystery 2 Codes (October 2020)

Our MM2 Codes post has the most updated list of codes that you can redeem for free knife skins. These codes don't do much for you in the game, but collecting different knife cosmetics is one of the fun aspects of playing this one!

Murder Mystery 2 Codes

In Murder Mystery 2 you will take up the role of either an Innocent, Sheriff, or Murderer! The Innocents will need to run, hide, and evade the Murderer and hopefully eventually use your sleuthing skills to figure out which player is the murderer! The Sheriff seeks to work with the Innocents to discover who the Murderer ends up being. If you're the Sheriff, you will be the only other player with a weapon, so you can take down the Murderer if you figure out who it is. The Murderer is the main bad guy of this scenario and is looking to eliminate any player who crosses their path. You'll want to try to be sneaky so you aren't discovered, and look to avoid being shot by the Sheriff!

  9. all of them ARE EXPIRED. THIS IS A SCAM!

    1. first off, if it is a scam then how come all of the EXPIRED codes are really EXPIRED CODES, and they don’t have any other codes yet because the DEVELOPER HASN’T MADE ANY AGAIN YET.

    2. Man, players in the Roblox community need to learn what the word scam means. You also need to learn what the word EXPIRED means as well. There’s two sections on the page, one is for available codes and one is for expired codes. Expired means they no longer work, which is why under the available section it says THERE’S NO ACTIVE CODES!!!

      1. i 100% am with you, but, my gosh.

        1. This is a website, and it has many pages on it. I also cover a lot more games than just Roblox, so it takes a long time to keep everything up-to-date. It’s a full-time job.
